Abstract

Formaldehyde-induced fluorescence histochemistry demonstrates three kinds of monoamine-containing cells in the normal finch pancreas. Most islet cells have weak fluorescence of intermediate color between yellow and green, suggesting the storage of both catecholamine and indolamine. These cells take up precursors of amines and related compounds. A small number of cells have intense blue-green fluorescence of catecholamine, but the type of the cells is unknown. Very few cells have intense yellow fluorescence, and at least some of them are 5-hydroxytryptamine-containing enterochromaffin cells.
